Whilst it is probably not earth shattering injury news, some people like to read if one of the players actually "sneeze" at training. For all we know, Sylvia was probably just saying he was a "bit stiff", that's all. Then had a lengthy spell in the loo.
He's reported what he has seen. If it's not enough for you, that's fine. By the way whilst it may be a little misleading it's hardly "alarmist" IMO.
